Final answer:
The Arabian Plate pushing into the Eurasian Plate forms a convergent thrust boundary, resulting in the creation of mountains such as the Zagros Mountains.
Step-by-step explanation:
The Arabian Plate pushing into the Eurasian Plate, creating mountains, is an example of a convergent thrust boundary. In this type of boundary, the two plates collide and one plate is forced beneath the other, resulting in the formation of mountains. The collision between the Arabian Plate and the Eurasian Plate has led to the formation of the Zagros Mountains.
